Earlier, people who wanted to get rid of spectacles had limited options and the only way they had was to wear contact lenses. The contact lenses option was never a convenient way and lot of care was required to be taken. With introduction of laser beam, it has become possible to undergo Lasik surgery and the best thing about this innovation is that Lasik surgery cost is extremely low. This has made possible for the people to throw off their glasses and enjoy a convenient life. As Lasik surgery cost is low, patients prefer to undergo this surgery and can even go to work.
This Lasik technology was first introduced way back in 1960 by a Spanish ophthalmologist. At that time, he developed the first microkeratome which was used to change the shape of cornea and cut thin flaps in the cornea region. With more research in this field this Lasik surgery cost has become popular and affordable. Now Lasik eye surgery can be performed within a span of a few minutes with help of laser. Those planning to go for this operation are advised to stop wearing contact lenses 10-15 days from the date of operation. Plain laser surgery includes Epi-laser as well.
Lasik eye surgery is performed in 2 stages. In the first step a flap of corneal tissue is created in which corneal suction ring is applied to the patients eye. In this process, sometimes, blood vessel gets burst and it results in bleeding, though gets resolved within few weeks. In the second step, excimer laser is used to remodel the corneal stroma. The Lasik surgery in this stage is used for vaporization of tissues in a controlled manner and then layers of tissues are removed which are tens of micrometers thick. At the second stage, the patient's vision becomes blurry and he or she is able to see only white light around the laser.
Lasik eye surgery has taken many forms. One of its forms are Wavefront guided Lasik wherein an ophthalmologist applies computers guided and guided excimer laser and it has measurements from a wavefront sensor laser technology. The goal of this is to restore perfect vision in the patient's eyes. This technology does not result in super vision or cures the eye defect 100%. Lasik doctors have claimed that patients with this form of surgery are more satisfied than with the previous methods. With the advantage of lower Lasik surgery cost and easier surgery, this method is really becoming popular.
